 		 #179767 - Feature Creep
Responding to: ???'s previous message
Per Westermark said:
But the user who did select an ARM chip with 32 or 64kB flash instead of 8 or 16kB for a 8051 has the advantage that if a customer calls and wonders if he can create a custom edition of the device with just a couple of new features will be able to say yes. He got the extra kilobytes of RAM and flash without extra cost. But the extra space means that the unit is extendable without any redesign.

I quite often get requests to add significant additions to existing products years after they were released. Then it is very good if I can switch to a pincompatible big brother...

We see frequent posts here where people have designed themselves into a corner by choosing a chip barely sufficient for the initial requirement - they are then stuck when extra features are requested.

Also when the the requirements have grown beyond not just particular chips, but the capabilities of the 8051 architecture itself.

               Fresh blood is needed            01/01/70 00:00      
   the closest thing to ...            01/01/70 00:00      
      But related to Keil tools            01/01/70 00:00      
         not really policed - yet...            01/01/70 00:00      
            Actually well policed and few to answer            01/01/70 00:00      
               "Policed"? [ed]            01/01/70 00:00      
                  Not by Keil            01/01/70 00:00      
                     Agreed.            01/01/70 00:00      
                        what I said            01/01/70 00:00      
                        That's what should happen here            01/01/70 00:00

         re: typo -- or intention?            01/01/70 00:00      
   But there's ARMs and ARMs...            01/01/70 00:00      
      Definitely too large span of ARM chips            01/01/70 00:00      
         many of the concepts in use with 8051 chips are applicable            01/01/70 00:00      
         the problem with 'embedded'            01/01/70 00:00      
            It's the small side that is i need of a forum            01/01/70 00:00

      I suppose you're right ...            01/01/70 00:00      
         Metric to use depends on past experiences            01/01/70 00:00      
            apply the right parametres            01/01/70 00:00      
               once again, I have to agree            01/01/70 00:00      
                  There's lot of analysis involved - about money            01/01/70 00:00      
                     Yes, that's all true for the PC world ... but what about us?            01/01/70 00:00      
            Feature Creep            01/01/70 00:00      
               Often easier to shrink after you have a product            01/01/70 00:00      
                  Absolutely!            01/01/70 00:00      
                     Isn't that a product of poor analysis?            01/01/70 00:00      
                        If requirements are properly analysed...            01/01/70 00:00      
                        no, it is a result of 'poor' customers            01/01/70 00:00      
                           Don't (necessarily) blame the customers!            01/01/70 00:00      
                              no blame of the customer            01/01/70 00:00

                                          You are still just the machine shop with ready blue prints            01/01/70 00:00      
                                             You can't engineer an enigma            01/01/70 00:00

                                                      See? Now here's a guy who knows how to solve the problem            01/01/70 00:00

                                                            Not exactly ...            01/01/70 00:00      
                                                   I think you're confusing marketing with engineering            01/01/70 00:00      
                                                      and neither have you            01/01/70 00:00

                                    Contract            01/01/70 00:00      
                              Yes, it's true, but educating them should be their cost.            01/01/70 00:00      
                           I have to disagree ... provisionally            01/01/70 00:00      
               I don't see that as a problem ...            01/01/70 00:00      
         No, they can't            01/01/70 00:00      
            That's true, but aren't most problems quite small?            01/01/70 00:00

      Yes, among others            01/01/70 00:00      
      Then that's a completely different question!            01/01/70 00:00
